• the carboxy functional siloxanes useful in this invention are well known types of materials whose general description and methods of preparation have been set forth in various places in the literature. Best results are believed to be obtained with a siloxane compolymer consisting essentially of about to 99 (preferably to 99) mole percent of units wherein R is selected from the group consisting of hydrocarbon, halohydrocarbon, cyanohydrocarbon, isocyanohydrocarbon, hydroxyhydrocarbon, mercaptohydrocarbon, etherhydrocarbon, esterhydrocarbon, thioetherhydrocarbon, thioesterhydrocarbon and nitrohydrocarbon radicals, and n has a value from 0 to 3, and about 1 to 25 (preferably 1 to 10) mole percent of R radical being ones wherein at least one of the R radicals is a methyl radical, at least 90 mole percent of all the siloxanes units in the copolymer having a degree of substitution of 2, and said siloxane copolymer having an overall degree of substitution in the
• the composition of this invention can contain from 1 to 50% by weight of the carboxy functional siloxane, but preferably contains from 3 to 30%
• the carboxy functional siloxanes employed herein can be used neat or in the form of a solution in an organic solvent or water. In the case of aqueous solutions, they can be mechanical emulsions of the siloxane copolymer or the emulsions obtained as a result of preparing the siloxane copolymer by emulsion polymerization. Preparation of these carboxy functional siloxane copolymers and the various types of solutions thereof are well known by those skilled in the art and will not be described in further detail here.

• composition of this invention can be applied to the textile to be treated in the same manner and using the same equipment as presently used for durable press resins alone. This is of great benefit to textile finishers as no new equipment need be purchased, and no radically new processing techniques need be learned by them. Of course, other methods of applying the composition to the textile can be used if so desired.
• compositions of this invention are best applied to the textile as a solution in a suitable organic solvent or as an aqueous emulsion.
• compositions and process of this invention can be used in conjunction with any textile but the advantages thereof are mostly readily apparent with certain types of textile. For example, improvement in flat appearance is best seen with lightweight materials such as batiste or shirtweight materials such as cotton/polyester blends whereas the ability to reduce the durable press resin needed is best seen with mediumweight materials such as poplin.
• a textile finishing composition was prepared which consisted essentially of 100 pounds of ethylene urea durable press resin (Proctor EU-SO), 24 pounds of magnesium chloride curing agent for the resin, 2 pounds of a nonionic polyether surfactant (Dexopal 555), 270 pounds of water, and 16 pounds of an emulsion consisting essentially of 35% of a siloxane copolymer consisting essentially of about 97.5 mole percent (CH SiO units and about 2.5 mole percent (CH )HOOCCH SCH CH S1O units, 2% of the ammonium salt of dodecylbenzenesulfonic acid, and 63% water.
• This composition was prepared by adding the surfactant to half the water, then adding the resin, next adding the siloxane emulsion, and finally adding the curing agent in the remaining amount of water. Continuous mild agitation was used during mix- Ihe above prepared composition was applied to about 100 yards each of nine difierent styles of polyester/cotton, lightweight fabrics, which ranged from batiste weight to dress good weight. In some of these fabrics the poly ester/cotton ratio was 65/35 and in others 50/50. The fabrics were padded single dip, dried in a foot frame at a speed of about yards per minute at temperature stages of 300, 330 and 360 F.
• the hand of the fabrics treated by the above process was extremely desirable.
• the average flat appearance of the fabrics without any treatment (AATCC Test Method 124-1967) was 1.8 after one wash and less than 3.0 after five washes whereas the treated fabrics averaged 3.7 after one wash and 4.2 after five washes.
• a textile finishing composition was prepared which consisted essentially of 100 pounds of ethylene urea durable press resin (Proctor EU-SOLF), 20 pounds of zinc chloride curing catalyst for the resin, 2 pounds of a nonionic surfactant (Actopal RS-l), 260 pounds of water, and 16 pounds of the siloxane copolymer emulsion used in Example 1.
• This formulation was designed to give about a 1% pick up of the siloxane copolymer based on the dry weight of the fabric on the average fabric run.
• the above composition was applied tovarious shirt fabrics running from lightweight batiste to mediumweight oxford weave fabrics.
• the fabrics were dipped and nipped once. The speed of operation was about yards per minute. After treatment the fabrics were dried in a 110 foot frame at the foregoing speed at temperature stages of 300, 330 and 360 F. for about /2 a minute.
